Introduction of YG43H / Y type high sensitivity steam pressure reducing valve

YG43H/Y型高灵敏度蒸汽减压阀 主要用于蒸汽管路,适用于进口压力变化大,流量变化大的蒸汽管路。 This YG43H / Y high-sensitivity steam pressure reducing valve is mainly used for steam pipelines, and is suitable for steam pipelines with large inlet pressure changes and large flow changes.
 
YG43H / Y type high sensitivity steam pressure reducing valve
 
I. Structural features and usefulness of YG43H / Y high-sensitivity steam pressure reducing valve:
 
固定比例式减压阀 属于先导活塞式减压阀。 This series of fixed proportional pressure reducing valve is a pilot piston pressure reducing valve. It consists of a main valve and a pilot valve. The main valve is mainly composed of valve seat, main valve disc, piston, spring and other parts. The pilot valve is mainly composed of valve seat, disc, diaphragm, spring, adjusting spring and other parts. The outlet pressure is set by adjusting and adjusting the spring pressure, the outlet pressure changes are sensed by the diaphragm, and the size of the over-flow area of the main valve throttling position is adjusted by the pilot valve opening and closing of the driving piston to realize the function of pressure reduction and pressure stabilization.
This series of products has made the following improvements on the basis of ordinary pressure reducing valves, increasing the area of the piston, changing the throttle structure, changing the sealing form, improving the structure of the pilot valve and adjusting the spring, thereby improving the product from the following aspects Performance.
1. Improved the sensing efficiency and sensitivity of outlet pressure changes, greatly reducing the pressure deviation caused by upstream pressure changes, flow changes and other factors.
2. Improved streamline distribution and reduced noise.
3. Improve the sealing surface structure and prolong the life of the sealing surface.
